NOTE: this vulnerability exists because of an\n incomplete fix for CVE-2016-7097 (bnc#1021258).\n - CVE-2016-7097: posix_acl: Clear SGID bit when setting file permissions\n (bsc#995968).\n - CVE-2016-10088: The sg implementation in the Linux kernel did not\n properly restrict write operations in situations where the KERNEL_DS\n option is set, which allowed local users to read or write to arbitrary\n kernel memory locations or cause a denial of service (use-after-free) by\n leveraging access to a /dev/sg device, related to block/bsg.c and\n drivers/scsi/sg.c. NOTE: this vulnerability exists because of an\n incomplete fix for CVE-2016-9576 (bnc#1017710).\n - CVE-2016-5696: TCP, when using a large Window Size, made it easier for\n remote attackers to guess sequence numbers and cause a denial of service\n (connection loss) to persistent TCP connections by repeatedly injecting\n a TCP RST packet, especially in protocols that use long-lived\n connections, such as BGP (bnc#989152).\n - CVE-2015-1350: Denial of service in notify_change for filesystem xattrs\n (bsc#914939).\n - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the\n Linux kernel did not validate the relationship between the minimum\n fragment length and the maximum packet size, which allowed local users\n to gain privileges or cause a denial of service (heap-based buffer\n overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).\n - CVE-2016-8399: An elevation of privilege vulnerability in the kernel\n networking subsystem could have enabled a local malicious application to\n execute arbitrary code within the context of the kernel. This issue is\n rated as Moderate because it first requires compromising a privileged\n process and current compiler optimizations restrict access to the\n vulnerable code. (bnc#1014746).\n - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the\n Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf,\n which allowed local users to cause a denial of service (memory\n corruption and system crash)\n or possibly have unspecified other impact by leveraging the\n CAP_NET_ADMIN capability for a crafted setsockopt system call with the\n (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531).\n -

CVE-2015-8962: Double free vulnerability in the sg_common_write function\n in drivers/scsi/sg.c in the Linux kernel allowed local users to gain\n privileges or cause a denial of service (memory corruption and system\n crash) by detaching a device during an SG_IO ioctl call (bnc#1010501).\n - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in\n the Linux kernel lacks chunk-length checking for the first chunk, which\n allowed remote attackers to cause a denial of service (out-of-bounds\n slab access) or possibly have unspecified other impact via crafted SCTP\n data (bnc#1011685).\n - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop\n function in block/genhd.c in the Linux kernel allowed local users to\n gain privileges by leveraging the execution of a certain stop\n operation even if the corresponding start operation had failed\n (bnc#1010716).\n - CVE-2016-7911: Race condition in the get_task_ioprio function in\n block/ioprio.c in the Linux kernel allowed local users to gain\n privileges or cause a denial of service (use-after-free) via a crafted\n ioprio_get system call (bnc#1010711).\n - CVE-2013-6368: The KVM subsystem in the Linux kernel allowed local users\n to gain privileges or cause a denial of service (system crash) via a\n VAPIC synchronization operation involving a page-end address\n (bnc#853052).\n - CVE-2015-8964: The tty_set_termios_ldisc function in\n drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to\n obtain sensitive information from kernel memory by reading a tty data\n structure (bnc#1010507).\n - CVE-2016-7916: Revert &quot;proc: prevent accessing /proc/&lt;PID&gt;/environ until\n it's ready (bsc#1010467)&quot;\n - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the\n Linux kernel allowed local users to cause a denial of service (OOPS) by\n attempting to trigger use of in-kernel hash algorithms for a socket that\n has received zero bytes of data (bnc#1010150).\n - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel before 4.8.7,\n in certain unusual hardware configurations, allowed remote attackers to\n execute arbitrary code via crafted fragmented packets (bnc#1008833).\n - CVE-2016-7042: KEYS: Fix short sprintf buffer in /proc/keys show\n function (bsc#1004517).\n - CVE-2015-8956: Bluetooth: Fix potential NULL dereference in RFCOMM bind\n callback (bsc#1003925).\n - CVE-2016-7117: net: Fix use after free in the recvmmsg exit path\n (bsc#1003077).\n\n The following non-security bugs were fixed:\n\n -

CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the\n Linux kernel allowed local users to obtain sensitive physical-address\n information by reading a pagemap file (bnc#994759).\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in\n drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a\n certain length field, which allowed local users to gain privileges or\n cause a denial of service (heap-based buffer overflow) via an\n ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in\n the Linux kernel did not properly maintain certain SACK state after a\n failed data copy, which allowed local users to cause a denial of service\n (tcp_xmit_retransmit_queue use-after-free and system crash) via a\n crafted SACK option (bnc#994296).\n\n The following non-security bugs were fixed:\n\n -

An unprivileged local\n user with access to SUID (or otherwise privileged) PIE\n binary could use this flaw to escalate their privileges\n on the system. (CVE-2017-1000253)\n\n - A use-after-free flaw was found in the way the Linux\n kernel's Datagram Congestion Control Protocol (DCCP)\n implementation freed SKB (socket buffer) resources for a\n DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option\n is set on the socket. A local, unprivileged user could\n use this flaw to alter the kernel memory, allowing them\n to escalate their privileges on the system.\n (CVE-2017-6074)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"http://security.gd-linux.com/notice/NS-SA-2019-0113\");\n script_set_attribute(attribute:\"solution\", value:\n\"Upgrade the vulnerable CGSL kernel packages.

vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).\n\n - CVE-2017-5551: tmpfs: Fixed a bug that could have allowed users to set setgid bits on files they don't down (bsc#1021258).\n\n - CVE-2016-10147: crypto/mcryptd.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5) (bnc#1020381).\n\n - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and

the Linux kernel did not check whether a batch message's length field is large enough, which allowed local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability (bnc#1010444).\n\n - CVE-2016-8645: The TCP stack in the Linux kernel mishandled skb truncation, which allowed local users to cause a denial of service (system crash) via a crafted application that made sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969).\n\n - CVE-2016-9806: Race condition in the netlink_dump function in net/netlink/af_netlink.c in the Linux kernel allowed local users to cause a denial of service (double free) or possibly have unspecified other impact via a crafted application that made sendmsg system calls, leading to a free operation associated with a new dump that started earlier than anticipated (bnc#1013540 1017589).\n\n - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and

dereference in mpi_powm() [ver #3] (bsc#1011820).\n\n - net: introduce __sock_queue_rcv_skb() function (bsc#1009969).\n\n - netback: correct array index (bsc#983348).\n\n - netfront: do not truncate grant references.\n\n - netfront: use correct linear area after linearizing an skb (bsc#1007886).\n\n - reiserfs: fix race in prealloc discard (bsc#987576).\n\n - rose: limit sk_filter trim to payload (bsc#1009969).\n\n - scsi: bfa: Increase requested firmware version to 3.2.5.1 (bsc#1013273).\n\n - xenbus: correctly signal errors from xenstored_local_init() (luckily none so far).\n\n - xenbus: do

script_set_attribute(\n attribute:\"description\", \n value:\n\"The openSUSE Leap 42.1 kernel to 4.1.38 to receive various security\nand bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2016-7117: Use-after-free vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux\n kernel allowed remote attackers to execute arbitrary\n code via vectors involving a recvmmsg system call that\n is mishandled during error processing (bnc#1003077).\n\n - CVE-2017-5551: tmpfs: Fixed a bug that could have\n allowed users to set setgid bits on files they don't\n down (bsc#1021258).\n\n - CVE-2016-10147: crypto/mcryptd.c in the Linux kernel\n allowed local users to cause a denial of service (NULL\n pointer dereference and system crash) by using an AF_ALG\n socket with an incompatible algorithm, as demonstrated\n by mcryptd(md5) (bnc#1020381).\n\n - CVE-2016-10088: The sg implementation in the Linux\n kernel did not properly restrict write operations in\n situations where the KERNEL_DS option is set, which\n allowed local users to read or write to arbitrary kernel\n memory locations or cause a denial of service\n (use-after-free) by leveraging access to a /dev/sg\n device, related to block/bsg.c and drivers/scsi/sg.c.\n NOTE: this vulnerability exists because of an incomplete\n fix for CVE-2016-9576 (bnc#1017710).\n\n - CVE-2016-7917: The nfnetlink_rcv_batch function in\n net/netfilter/nfnetlink.c in the Linux kernel did not\n check whether a batch message's length field is large\n enough, which allowed local users to obtain sensitive\n information from kernel memory or cause a denial of\n service (infinite loop or out-of-bounds read) by\n leveraging the CAP_NET_ADMIN capability (bnc#1010444).\n\n - CVE-2016-8645: The TCP stack in the Linux kernel\n mishandled skb truncation, which allowed local users to\n cause a denial of service (system crash) via a crafted\n application that made sendto system calls, related to\n net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c\n (bnc#1009969).\n\n - CVE-2016-9806: Race condition in the netlink_dump\n function in net/netlink/af_netlink.c in the Linux kernel\n allowed local users to cause a denial of service (double\n free) or possibly have unspecified other impact via a\n crafted application that made sendmsg system calls,\n leading to a free operation associated with a new dump\n that started earlier than anticipated (bnc#1013540\n 1017589).\n\n - CVE-2016-9793: The sock_setsockopt function in\n net/core/sock.c in the Linux kernel mishandled negative\n values of sk_sndbuf and sk_rcvbuf, which allowed local\n users to cause a denial of service (memory corruption\n and system crash) or possibly have unspecified other\n impact by leveraging the CAP_NET_ADMIN capability for a\n crafted setsockopt system call with the (1)\n SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531\n 1013542).\n\nThe following non-security bugs were fixed :\n\n - PCI: generic: Fix pci_remap_iospace() failure path\n (bsc#1019658).\n\n - bcache: partition support: add 16 minors per bcacheN\n device (bsc#1019784).\n\n - bnx2x: Correct ringparam estimate when DOWN\n (bsc#1020214).\n\n - clk: xgene: Do not call __pa on ioremaped address\n (bsc#1019660).\n\n - kABI workaround for 4.1.37 mount changes\n (stable-4.1.37).\n\n - kABI: reintroduce sk_filter (bsc#1009969).\n\n - kabi/severities: Ignore inode_change_ok change It's\n renamed in 4.1.37 to setattr_prepare()\n\n - mpi: Fix NULL ptr dereference in mpi_powm() [ver #3]\n (bsc#1011820).\n\n - net: introduce __sock_queue_rcv_skb() function\n (bsc#1009969).\n\n - netback: correct array index (bsc#983348).\n\n - netfront: do not truncate grant references.\n\n - netfront: use correct linear area after linearizing an\n skb (bsc#1007886).\n\n - reiserfs: fix race in prealloc discard (bsc#987576).\n\n - rose: limit sk_filter trim to payload (bsc#1009969).\n\n - scsi: bfa: Increase requested firmware version to\n 3.2.5.1 (bsc#1013273).\n\n - xenbus: correctly signal errors from\n xenstored_local_init() (luckily none so far).\n\n - xenbus: do not invoke ->is_ready() for most device\n states (bsc#987333).\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.opensuse.org/show_bug.cgi?id=1003077\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n* It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.\n(CVE-2016-9576, CVE-2016-10088, Moderate)\n\n* A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object.

(CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic.

available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the / proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n* It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nSecurity Fix(es) :\n\n* It was discovered that a remote attacker could leverage the\ngeneration of IPv6 atomic fragments to trigger the use of\nfragmentation in an arbitrary IPv6 flow (in scenarios in which actual\nfragmentation of packets is not needed) and could subsequently perform\nany type of a fragmentation-based attack against legacy IPv6 nodes\nthat do not implement RFC6946. (CVE-2016-10142, Moderate)\n\n* A flaw was discovered in the way the Linux kernel dealt with paging\nstructures. When the kernel invalidated a paging structure that was\nnot in use locally, it could, in principle, race against another CPU\nthat is switching to a process that uses the paging structure in\nquestion. A local user could use a thread running with a stale cached\nvirtual->physical translation to potentially escalate their privileges\nif the translation in question were writable and the physical page got\nreused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in\nthe Linux kernel's aacraid implementation. A local attacker could use\nthis flaw to cause a denial of service (out-of-bounds access or system\ncrash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading\nthe / proc/keys file could cause a panic in the Linux kernel due to\nstack corruption. This happened because an incorrect buffer size was\nused to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042,\nModerate)\n\n* It was found that when file permissions were modified via chmod and\nthe user modifying them was not in the owning group or capable of\nCAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via\nsetxattr sets the file permissions as well as the new ACL, but doesn't\nclear the setgid bit in a similar way. This could allow a local user\nto gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local\nattacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds\nmemory access by creating a smaller-than-expected ICMP header and\nsending to its destination via sendto(). (CVE-2016-8399, Moderate)\n\n* It was found that the blk_rq_map_user_iov() function in the Linux\nkernel's block device implementation did not properly restrict the\ntype of iterator, which could allow a local attacker to read or write\nto arbitrary kernel memory locations or cause a denial of service\n(use-after-free) by leveraging write access to a /dev/sg device.\n(CVE-2016-9576, CVE-2016-10088, Moderate)\n\n* A flaw was found in the USB-MIDI Linux kernel driver: a double-free\nerror could be triggered for the 'umidi' object. An attacker with\nphysical access to the system could use this flaw to escalate their\nprivileges.

A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.\n\n - A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n\n - A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object. An attacker with physical access to the system could use this flaw to escalate their privileges.\n\nNote that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory.\nTenable has attempted to automatically clean and format it as much as possible without introducing additional issues.", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2017-03-31T00:00:00", "type": "nessus", "title": "Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-025)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": true, "obtainUserPrivilege": false}, "cvelist": ["CVE-2016-10088", "CVE-2016-10142", "CVE-2016-2069", "CVE-2016-2384", "CVE-2016-6136", "CVE-2016-6480", "CVE-2016-6828", "CVE-2016-7042", "CVE-2016-7097", "CVE-2016-8399", "CVE-2016-9555", "CVE-2016-9576", "CVE-2017-6214"], "modified": "2021-01-04T00:00:00", "cpe": ["p-cpe:/a:virtuozzo:virtuozzo:parallels-server-bm-release", "p-cpe:/a:virtuozzo:virtuozzo:vzkernel", "p-cpe:/a:virtuozzo:virtuozzo:vzkernel-devel", "p-cpe:/a:virtuozzo:virtuozzo:vzkernel-firmware", "p-cpe:/a:virtuozzo:virtuozzo:vzmodules", "p-cpe:/a:virtuozzo:virtuozzo:vzmodules-devel", "cpe:/o:virtuozzo:virtuozzo:6"], "id": "VIRTUOZZO_VZA-2017-025.NASL", "href": "https://www.tenable.com/plugins/nessus/99106", "sourceData": "#%NASL_MIN_LEVEL 70300\n#\n# (C) Tenable Network Security, Inc.\n#\n\ninclude('deprecated_nasl_level.inc');\ninclude('compat.inc');\n\nif (description)\n{\n script_id(99106);\n script_version(\"3.9\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2021/01/04\");\n\n script_cve_id(\n \"CVE-2016-10088\",\n \"CVE-2016-10142\",\n \"CVE-2016-2069\",\n \"CVE-2016-2384\",\n \"CVE-2016-6136\",\n \"CVE-2016-6480\",\n \"CVE-2016-6828\",\n \"CVE-2016-7042\",\n \"CVE-2016-7097\",\n \"CVE-2016-8399\",\n \"CVE-2016-9555\",\n \"CVE-2016-9576\",\n \"CVE-2017-6214\"\n );\n\n script_name(english:\"Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-025)\");\n script_summary(english:\"Checks the rpm output for the updated packages.\");\n\n script_set_attribute(attribute:\"synopsis\", value:\n\"The remote Virtuozzo host is missing multiple security updates.\");\n script_set_attribute(attribute:\"description\", value:\n\"According to the versions of the parallels-server-bm-release /\nvzkernel / etc packages installed, the Virtuozzo installation on the\nremote host is affected by the following vulnerabilities :\n\n - A flaw was found in the Linux kernel's handling of\n packets with the URG flag.

(CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request.

An attacker can leverage the\n generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of\n fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing\n fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed,\n unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to\n DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS\n scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they\n implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause\n a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large\n command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write\n function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain\n privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2\n does not restrict a certain length field, which allows local users to gain privileges or cause a denial of\n service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does\n not properly initialize a certain data structure, which allows attackers to obtain sensitive information\n from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations,\n allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not\n properly randomize the legacy base address, which makes it easier for local users to defeat the intended\n restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or\n setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to\n cause a denial of service (system crash) via a crafted application that makes sendto system calls, related\n to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1\n allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system\n crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in\n required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have\n unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x\n before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a\n large iov_count value in a write request.
